the use of the endplate or end sill. When used in open top cars(gondolas) the corner post could be dispensed with. 1

Another object of the invention is to form a wall of a railway car oftwo plates secured together along a horizontal line and to form anintegral post ad acent each vertical margin thereof and to reinforce thecon- 7 nection between the two plates at each core ner post. I

-In the drawmgs: I 'Fig; 1 shows a'ra1lway Fig. 2is'a side elevation ofFig. 1.

Fig. '3 is a section on line 3-3 of Fig. 1.

Fig. 4 is a perspective View of a metallic plate having an integralcorner post formed thereln and reinforced according to my in vention. r

Fig. 5 is a modification of Fig. 1.

Fig. 6 shows-the plate of Fig. 5 without the reinforcement.

Figs. 1 to 4 inclusive show my invention 1 applied to a railway box carwherein the metallic plate 1 forming the end Wall of the car is providedwith an integral Z shape mem-.

ber adjacent each of its opposite vertical margins, which members aresecured to the upper side plates 2 and lower side SlllS 3, respectively,on each slde of the car, thus forming the usual corner post, that 1s,the integral Z shape formation or members performs the functions of theusual corner post of the car. (This construction is disclosed andclaimed in my co-pending application Serial No. 308,102, filed September24, 1928.)

would eliminate boxcar equipped V with a typical application ofmydevice.

Each Z shape member comprises a web' l,

an outer flange 5 and an inner flange 6. Such a Z shape constructionprovides a very strong column to resiststresses longitudinally of itslength, and furthermore, such a Z-shape conq;

structi'on forms a very efficient 'beam'to resist stresses normal to itslength. This statement is true whether the stressesare parallel totheweb, normal to the web or diagonal thereto, therefore, such a Z shapefor- '3;

mationforms a Very eflicient corner post construction. v 1

When a member'is subjected to columnar stresses or beam stresses, themaximum fibre stress occurs adjacent the middle of the memher, and as aco rner post (orin fact any post in'a railway car) is subjected to bothof such stresses, I' prefer to reinforce the middle portion of theintegral corner post with areinforcing sheet havinga portion secured tothe body ofthe sheet at'8 and a portion secured to the outer flange at-9 and a straight portion 10 connectingthe portions 8 and 9, as shown inFig. 3. These reinforcing sheets may comprise a' plurality of narrowbands :15

11, as shown in Figs. 1 and2, or may comprise a relatively wide sheet 7,as shown in Figs. 4 and 5. g

I prefer to extend the reinforcing sheet or she'etslbeyond-the outerflange 5 of the L.

plate and secure them to the longitudinal. girths or other frame membersof'the car, thus tying the end wall to thesegirths and furthermore tyingthe girths together.

In the opinion of some engineers it may i T be objectionable to have thediagonal portion '10 ofthe reinforcing sheet 7 spaced away from theintegral corner post, as such a constructionwould'permit moisture orsnow to get'behind the reinforcing sheet, therefore, in Fig. 5 I haveshown a constructionwherein'the end portions 15 are extended and'formedto fit into the contour of the integral corner post, thus closing one(or both) oftheends of, the reinforcing plate.

I prefer to'seeure these extended ends to the web 4 by rivets 16 andinner flange 6 by rivets 17, respectively, of the Z shape corner post.to'seeureunity of action therebe-, M

tween under stress.

A great many car ends are now in service comprising an upper and lowermetallic plate secured together along horizontal lines and havingintegral horizontal corrugations in each sheet and such sheets aresecured along their vertical edges to the corner posts of the car whichextend continuously from sill to plate of the car. WVhen an integralcorner post is formed in such a construction (as shown in Fig. l) a weakplace is formed where the two plates are secured together because theriveted connection is not as strong as other portions of the integralcorner post, therefore, when the end wall comprises two metallic platessecured together along horizontal lines and form an integral corner postI prefer to so position the reinforcing sheet that it spans the junctureof the sheets and is secured to both of said sheets and the width ofsuch reinforcing sheet could be extended to develop the strength of theintegral corner postaccording to known methods of caiculating columnsand beams. Vhen such sheets are provided with horizontal integralcorrugations or embossments 19 I prefer to terminate them into the plateadjacent the reinforcing sheet, as shown at 20 in Fig. 4.

The accompanying drawings illustrate the preferred form of theinvention, though it is to be understood that the invention is notlimited to the exact details of construction sho *n and described, as itis obvious that various modifications thereof within the scope of theclaims will occur to persons skilled in the art.
